No, I don't think so. However, the cat's sharp claws are more likely to tear the net.

I use the bag for a dog and am very satisfied. However, I once had an experience with my cat when she opened her bag on the plane while I was out of my seat. She then went for a walk on the plane. I therefore recommend connecting the zip sliders with a small lock if the cat has to be left unattended in the bag.

Have dog, no idea

In theory, if the bag is closed properly, no. I use it for the dog, if the zips are tightly closed he can't open them.

My dog didn't make it.
